The introduction to the song was an excerpt of an original song that the group had in its act--Phillips added it to "Blue Moon" to give it a flair that the group was lacking in their other songs. The Marcels recorded this in two takes. A promotion man asked and got a copy of the finished tape, which found its way to legendary DJ 'Murray The K' (qv). He promoted it as an "exclusive" and played it 26 times on one show.

In August 1961, due to racial problems encountered in the Deep South while touring because of the group being multi-racial, Knauss and Bricker--the group's white members--left and were replaced by Allen Johnson (brother of Fred) and Walt Maddox. Mundy left soon after, leaving the group a quartet. In 1962 Harp and Allen Johnson left, and were replaced by Richard Harris and William Herndon. There was a brief reunion of the original members in 1973. The group made several recordings in 1975 with Harp back on lead. Original member Gene Bricker died in 1983. Allen Johnson died in 1995. By the early 1990s the group included Johnson, Maddox, Harris, Jules Hopson, and Richard Merritt. The group split around 1995. Fred Johnson formed his own group with new members, while the other four members recruited new bassist Ted Smith. Maddox won a lawsuit against Sunny James Svetnic, the manager of Johnson's group, for trademark infringement in 1996.[citation needed] Johnson reunited with Harp, Mundy and Knauss in 1999 for the PBS special Doo Wop 50.

The Marcels' popularity in 1961 was so great that they were included in the Oscar Rudolph film Twist Around the Clock. Released on December 30, 1961, with the tagline "It's Twist-eriffic! The first full-length movie about the Twist!" the film also showcased fellow artists Chubby Checker, Dion DiMucci, Vicki Spencer and singer-songwriter and TV show host turned actorClay Cole. Allen Johnson, Gene Bricker, Cornelius Harp, Fred Johnson, Richard Knauss and Ronald Mundy of The Marcels were all included--and had speaking parts in addition to performing musical numbers. They sing "Merry Twist-Mas", which was released over Christmas 1961, though no chart action ensued.

This Annette Funicello and Frankie Avalon movie, about a millionaire who sets out to prove his theory that his pet chimpanzee is as intelligent as the teenagers who hang out on the local beach where he is intending to build a retirement home but ends in hilarious results, also included two of The Marcels, Gene Bricker and Cornelius Harp. They provided backing vocals for two songs, Avalon's "Gimme Your Love Yeah Yeah Yeah" and Little Stevie Wonder's "(Happy Feelin') Dance And Shout".
